Overview
The UCC21732DWR is a galvanically isolated single-channel gate driver from Texas Instruments, designed for SiC MOSFETs and IGBTs with operating voltages up to 2121V DC. It features a 5.7-kVrms isolation rating and provides +/-10A peak drive current. The device operates within a temperature range of -40°C to +125°C and is housed in a 16-pin SOIC package. Key electrical parameters include a maximum propagation delay of 130 ns, rise time of 28 ns, and fall time of 24 ns. Power dissipation is rated at 985 mW, and it supports both inverting and non-inverting configurations.
Feature Summary
- Galvanic isolation with 5.7-kVrms rating for high-voltage applications
- High peak output current capability of +/-10A for fast switching
- Advanced protection features including active short circuit protection
- Automotive qualification compliant with AEC-Q100 standards
Applications
- SiC MOSFET gate driving in high-power converters
- IGBT gate driving in industrial motor drives
- Automotive power electronics systems
- Isolated DC-DC converter control circuits
Procurement Notes
Verify the specific suffix 'DWR' corresponds to the SOIC-16 package and tape-and-reel packaging configuration. Confirm that the automotive grade designation is required for your application, as standard versions may lack AEC-Q100 certification. Check for moisture sensitivity level requirements during storage and handling. Ensure the design supports the 13V to 33V supply voltage range specified for proper operation.
Selection Notes
Select this component when high dv/dt immunity and robust isolation are required for wide-bandgap semiconductors. The single-channel architecture simplifies layout compared to dual-channel alternatives. Consider the 130 ns propagation delay limit when designing timing-critical circuits. The SOIC-16 package offers a balance between thermal performance and board space efficiency for medium-density designs.
Part Context
The UCC21732 belongs to Texas Instruments' UCC217xx family of isolated gate drivers. This series utilizes capacitive coupling technology to provide signal transmission across the isolation barrier. The DWR variant specifically denotes the surface-mount SOIC-16 package form factor. It serves as a core interface component bridging low-voltage control logic with high-voltage power stages.
Replacement Considerations
The UCC21732QDWRQ1 is the automotive-qualified version of this component. Verify if AEC-Q100 certification is mandatory for your specific application before substituting. Both parts share identical electrical characteristics and pinouts.
